Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to vacuum-gas replacement grinding and continuous packaging processing apparatuses for preventing oxidation of foods,

More particularly, the present invention relates to a vacuum-gas replacement milling and continuous packaging machine for preventing oxidation of foods, and more particularly, , Which can prevent oxidative and browning reactions that may occur during processing, packaging and distribution of food, thereby preventing deterioration of the quality of food. And a continuous package processing apparatus.

Antioxidants are a generic term for substances that prevent oxidation, and it has become known that active oxygen is involved in various diseases. Foods include polyphenols, vitamin C, vitamin E, and beta-carotene. Some foods contain a variety of substances that have antioxidant properties. One of them is polyphenol compounds which have two or more hydroxyl groups. Vitamin C, vitamin E, and β-carotene have antioxidant properties and are called antioxidant vitamins.

Fruits are rich in phenolic compounds known as antioxidants. However, phenolic compounds are easily oxidized by binding to oxygen in the air, and a significant amount of phenolic compounds are denatured during processing of the fruit. Particularly, when processing fruits and the like at a small size, the phenol component easily oxidizes as the surface area becomes wider

In general, apple, banana, grape, and other fruits and vegetables come into contact with oxygen and oxidize to deteriorate quality. Especially, these fruits and vegetables contain polyphenol materials, so they react with an enzyme called polyphenol oxidase due to oxygen contact Browning occurs, and the antioxidative activity is also decreased.

This phenomenon is one of the most important quality deterioration factors in raw materials for fruit and vegetables and various food processing, and it is very important to suppress these phenomena.

Conventional vegetable processing methods for preventing browning include a method of using a browning inhibitor such as vitamin C during processing, a method of suppressing oxidation by replacing oxygen by nitrogen injection, and the like, and they are immersed in brine or sugar water Use or storage.

However, in the conventional vegetable processing method, there is a problem in that, in order to suppress the browning phenomenon, an expensive nitrogen substitution device is used in a food processing factory and a production company, or other artificial additives are used in combination.

In addition, it is very important to prevent contact with oxygen in the pulverization process when the fruits and vegetables are processed into foods, since the flesh of the fruits and vegetables is crushed during the crushing process during the fruit and vegetable processing, and the surface area in contact with oxygen is widened and browning is accelerated .

According to Korean Utility Model Registration No. 20-0203484, a blender capable of processing food can be used. Since the food is processed in a state where oxygen is contained in the container for storing the food, the food is easily oxidized .
